As shown in fig. 1, an application scenario according to an embodiment of the present disclosure includes a drone 100 and a testing device 200.
The unmanned aerial vehicle 100 may be, for example, a fixed-wing unmanned aerial vehicle or a multi-rotor unmanned aerial vehicle, and the multi-rotor unmanned aerial vehicle is taken as an example in fig. 1, but it is understood that the present disclosure is not limited to a specific type of the unmanned aerial vehicle 100.
The unmanned aerial vehicle 100 comprises a motor 101 for driving a wing to work, and the testing device 200 can be specifically a motor testing device for testing the performance of the motor 101 such as tensile force, torsion and the like.

It will be appreciated that the particular configuration of the unmanned aerial vehicle, motor configuration and motor testing apparatus of fig. 1 is merely illustrative, and that unmanned aerial vehicles, motors and motor testing apparatus of any configuration may be selected according to particular needs.

Referring to fig. 2A-2C, a motor testing device 200 according to an embodiment of the disclosure includes a base 210, a support arm 220, a rotating shaft 230, and a rotating shaft fixing member 240.
The base 210 may have a plate-like structure, for example, and the rotating groove 213 may be disposed at a central position in a thickness direction of the plate-like structure, and the base 210 may have a rectangular structure, a semicircular cake-like structure, or the like, for example. It is to be understood that the shape and structure of the base 210 described above is merely exemplary to facilitate understanding of the present disclosure, and the present disclosure is not limited to the shape and structure of the base 210.
As shown in fig. 2C, the first end of the arm 220 is fixedly connected to the rotating shaft 230. Specifically, the first end of the arm 220 is provided with a first through hole 221, the size of the first through hole 221 is matched with the size of the rotating shaft 230, the arm 220 may be, for example, a plate-shaped structure, and the thickness of the plate-shaped structure is smaller than the thickness of the rotating groove 213 of the base 210 in the horizontal direction perpendicular to the extending direction thereof, so that the arm 220 may be inserted into the rotating groove 213.
A second end of the arm 220, opposite the first end, may have a securing structure for securing the motor 101, for example, for securing and supporting the motor 101, in accordance with embodiments of the present disclosure.
The rotation shaft 230 is disposed along a horizontal direction perpendicular to an extending direction of the rotation groove 213 of the base 210, and when the support arm 220 is inserted into the rotation groove 213, the rotation shaft 230 is also disposed in the rotation groove 213, and the rotation groove 213 may further have a fixing structure for fixing the rotation shaft 230, for example, so that the support arm 220 and the base 210 may be hinged after the rotation shaft 230 is inserted into the first through hole 221 of the support arm 220 and fixed by the fixing structure.
As shown in fig. 2B, according to an embodiment of the present disclosure, the base 210 may be further provided with, for example, a third through hole 215 in a horizontal direction perpendicular to the extending direction of the rotation groove 213, and the rotation shaft 230 may be disposed in the third through hole 215 when the base 210 and the arm 220 are hinged.
In the case that the rotation shaft 230 is disposed in the rotation groove 213 and passes through the first through hole 221 of the support arm 220 to hinge the support arm 220 with the base 210, one end of the rotation shaft fixing member 240 may extend from the second side 212 of the base 210 opposite to the first side 211 to the position of the rotation shaft 230, so as to fix or release the rotation shaft under the action of the first force.
In accordance with embodiments of the present disclosure, a shaft mount 240 may be provided to the base 210 and act on the shaft 230 to secure or release the shaft, for example. Specifically, the other end of the rotating shaft fixing member 240 opposite to the end extending to the rotating shaft 230 may protrude from the second side 212 of the base 210, so as to receive the first force. The first force may be, for example, a force applied by a tester through a wrench, a pliers, or the like, or may be a force directly applied by the tester, for example, the rotating shaft fixing member 240 may be rotated by a second force, so as to change a distance between the rotating shaft fixing member 240 and the rotating shaft 230, so as to fix and release the rotating shaft 230.
According to an embodiment of the present disclosure, the shaft fixing member 240 may be, for example, a fixing pin, which extends to one end of the shaft 230, or a structure near the one end extending to the shaft 230 may be, for example, a screw structure, and a portion of the base 210 near the second side 211 may have, for example, a screw structure matching the screw structure of the shaft 230, so as to facilitate insertion of the shaft fixing member 240. It should be understood that the structure of the rotating shaft fixing member 240 is merely exemplary to facilitate understanding of the disclosure, and the disclosure is not limited thereto, for example, the rotating shaft fixing member 240 may not have a threaded structure, and a portion of the base 210 near the second side 212 may be provided with a through hole into which the rotating shaft fixing member 240 may be inserted.
According to the embodiment of the disclosure, since the rotating shaft fixing member 240 can release or fix the rotating shaft 230 under the action of the first acting force, for example, in the case that the rotating shaft fixing member 240 releases the rotating shaft 230, the second acting force acting on the support arm 220 or the rotating shaft 230 can enable the support arm 220 and the rotating shaft 230 to rotate relative to the central axis of the rotating shaft 230, so as to change the included angle between the motor 101 supported by the support arm 220 and the horizontal plane, when the motor 101 rotates to a preset included angle with the horizontal plane, the rotating shaft fixing member 240 can be enabled to fix the rotating shaft 230 through the first acting force, so that the motor 101 can maintain the position of the preset included angle, and the performance parameters of the motor 101 in the state of the preset included angle can be conveniently measured, so that the performance test of the motor in different angle states can be realized, and the requirements of the performance test of the motor in the simulation of various working conditions can be satisfied.
According to the embodiment of the disclosure, the rotatable angle of the support arm 220 relative to the central axis of the rotating shaft 230 depends on the arrangement of the rotating groove 213 of the base 210, specifically, the angle formed by the side surface of the rotating groove 213 close to the second side 212 and the side surface extending from the first side 211 to the second side 212, in order to achieve the requirement of the motor performance test under all possible working conditions, the angle formed by the side surface of the rotating groove 213 close to the second side 212 and the side surface extending from the first side 211 to the second side 212 may be set to a value not less than 90 ° so that the rotatable angle of the support arm 220 about the central axis of the rotating shaft 230 in the rotating groove 213 under the action of the second action of the force is not less than 90 °, thereby driving the motor 101 to be in a state with any angle between 0 ° and 90 ° with respect to the horizontal plane, and meeting the requirement of the motor performance test under all working conditions.
Referring to fig. 2B again, the motor testing apparatus 200 of the embodiment of the disclosure may further include a first support arm and fixing member 250, and correspondingly, two opposite side walls of the base 210 forming the rotating slot 213 may be further provided with opposite guide slots 214, where the guide slots 214 are arc-shaped, and when the rotating shaft 230 is hinged to the support arm 220 and the base 210, a center point of the arc-shaped structure is on a central axis of the rotating shaft 230, and a position of the guide slots 214 is higher than a position of the rotating shaft 230 when the rotating shaft 230 is hinged to the support arm 220 and the base 210, specifically, the guide slots 214 are located at a second end of the base 210 near the support arm 220 opposite to the first end, compared to the rotating shaft 230, and more specifically, the guide slots 214 may be disposed along an extending direction of the rotating slot 213. The first arm fixture 250 may be threaded through the oppositely disposed two arcuate guide slots 214 of the base 210 to define the position of the arm 220 articulated to the base 210. Specifically, when the arm 220 is hinged to the base 210 through the rotation shaft 230, the first arm fixing member 250 may be detachably disposed in the set of curved guide grooves 214 at a position where the arm 220 is close to the side wall of the first side 211 of the base 210, so as to define the position of the arm 220.
As shown in fig. 2C, the first arm fixing member 250 may be a fixing pin structure with a threaded rod and a nut, for example, if the angle between the motor 101 and the horizontal plane needs to be changed in the process of testing the motor 101 by using the motor testing device 200, the first arm fixing member 250 may be rotated to release the clamping of the first arm fixing member 250 to the arm by rotating the nut of the first arm fixing member 250, meanwhile, the rotating shaft fixing member 240 may release the rotating shaft 230 by the first acting force, the arm may be rotated to a desired angle by the second acting force, and after the rotating shaft is rotated to the desired angle, the rotating shaft fixing member 240 may fix the rotating shaft 230 by the first acting force, and further limitation of the position of the arm 220 may be achieved by screwing the first arm fixing member 250, so as to ensure that the arm 220 may be firmly fixed to the desired angle of the tester. It should be understood that the structure and the use method of the first arm fixing member 250 are merely examples to facilitate understanding of the disclosure, and the disclosure is not limited thereto, as long as the limiting effect on the arm 220 can be achieved, and meanwhile, the rotation of the arm 220 is not affected.
Referring to fig. 2C, the motor testing device 200 may further include a second arm fixing member 260, where the second arm fixing member 260 may have the same structure or a different structure from the first arm fixing member 250. The second arm fixing member 260 is disposed through the guide slot 214 and the arm 220 to define a position of the arm 220. Specifically, the support arm 220 is further provided with a second through hole 222 near the first through hole 221 for penetrating the rotation shaft 230, the position of the second through hole 222 relative to the first through hole 221 corresponds to the position of the guide slot 214 relative to the third through hole 215 of the base 210, so that when the support arm 220 is hinged to the base 210, the position of the second through hole 222 corresponds to the position of the guide slot 214 on a set of arc tops, so that the second support arm fixing member 260 can penetrate through the second through hole 222 and the guide slot 214 at the same time, so as to further define the position of the support arm 220, wherein the sizes of the second support arm fixing member 260 and the first support arm fixing member 250 are determined by the size of the second through hole 222 of the support arm 220 and the size of the guide slot 214, which will not be described herein. It will be appreciated that, to ensure a secure attachment of the arm 220, the second through hole 222 of the arm 220 is sized to match the size of the guide slot 214 to ensure that the arm 220 does not rock in a vertical direction when the arm 220 is hinged to the base 210.
In the process of testing the motor 101 by the motor testing device 200, if the included angle of the motor 101 relative to the horizontal plane needs to be changed, the clamping of the first support arm fixing member 250 and the second support arm fixing member 260 to the support arm can be simultaneously released, meanwhile, the rotating shaft 230 is released by the rotating shaft fixing member 240 through the first acting force, so that the support arm rotates to a required angle under the action of the second acting force, after the support arm rotates to the required angle, the rotating shaft 230 is fixed by the rotating shaft fixing member 240 through the first acting force, and the position of the support arm 220 can be further limited by screwing the first support arm fixing member 250 and the second support arm fixing member 260, namely, the support arm 220 can be ensured to be firmly fixed at the required angle of a tester through the two support arm fixing members and one rotating shaft fixing member.
According to an embodiment of the present disclosure, in order to only further enhance the limiting and fixing effect of the second arm fixing member 260 on the arm, the second through hole 222 may be disposed at a position where the central axis of the arm 220 is located, for example, such that the second through hole 222 is in an axisymmetric structure with respect to the central axis of the arm 220.
In accordance with an embodiment of the present disclosure, as shown in fig. 2B, in a case where the second through hole 222 is provided at a position where the central axis of the arm 220 is located, a surface of either one of two opposite side walls of the base 210 forming the rotation groove 213 may be provided with an angle scale along the guide groove 214. Specifically, the first side wall may be provided with an angle scale, for example, in a range of 0 ° -90 °, for example, along the arcuate guide groove 214 on a surface remote from the second side wall, and the 0 ° -scale may be provided in a direction perpendicular to the extending direction of the rotating groove 213, and the 90 ° -scale may be provided in the extending direction of the rotating groove 213, for example, with an accuracy of 1 degree. It will be appreciated that the scale ranges, scale start positions, end positions, and accuracy of the angle scales described above are merely examples to facilitate understanding of the present disclosure, and the present disclosure is not limited thereto.
Considering that the second through hole 222 may be disposed at a position where the central axis of the support arm 220 is located, for example, the scale position where the second support arm fixing member 260 penetrating the second through hole 222 is located is the position where the central axis of the support arm is located, so that, according to the angle scale corresponding to the position where the second support arm fixing member 260 is located, the angle of rotation of the support arm 220 in the rotation slot 213 around the central axis of the rotation shaft 230 can be determined, and the initial position where the support arm 220 rotates relative to the central axis of the rotation shaft 230 may be set as, for example, the position where the support arm 220 is located in the vertical direction, or any other position, and then, according to the angle scale corresponding to the second support arm fixing member 260 when the support arm 220 is located at the initial position and the angle scale corresponding to the second support arm fixing member 260 where the support arm 220 is located at present, the angle of rotation of the support arm 220 can be determined, so that a tester can accurately determine the angle of rotation of the support arm 220, and thus accurately determine the angle between the motor 101 and the horizontal plane.
Fig. 3 schematically illustrates a structural exploded view of a motor testing device according to another embodiment of the present disclosure.
As shown in fig. 3, compared with the motor testing device described with reference to fig. 2C, the motor testing device of the embodiment of the disclosure is different in that the motor testing device 200 further includes a driving member 270, and an output shaft of the driving member 270 is fixedly connected with the rotating shaft 230 for providing a driving force to the rotating shaft 230 so as to rotate the rotating shaft 230 around the center axis, and since the rotating shaft 230 is disposed through the first through hole 221 of the support arm 220, when the driving member drives the rotating shaft 230 to rotate around the center axis, the rotating shaft 230 can provide a second acting force to the support arm 220, so that the support arm 220 rotates along with the rotating shaft 230 and also takes the center axis of the rotating shaft as the rotating shaft. The rotation shaft and the support arm are driven to rotate by the driving member 270, so that the accuracy of the rotation angle of the support arm can be improved compared with the technical scheme of manually applying the acting force.
